Subsea MicroDI®Logger

The MicroDI® (Micro Data Interface) data Logger is especially designed for rough environmental conditions and high-accuracy long-time measuring applications.

The main features are: ultra low power for long-time deployments, multiple high accuracy analogue inputs, and high precision real-time and high data storage capacity, small but robust pressure housing.

The RS-232 or RS-485 interfaces can be used for digital sensor signals and online real-time data output. The industrial microSD cards can be used for years to readout data on a computer. A high analogue data-sampling rate of up to 10 Hz supplies not only long-time monitoring applications but for instance also wave sampling. The ultra low-power consumption allows long-time monitoring. The modular hardware and flexible software enables optimized and customized solutions for your projects.
